DYNAMO OR MOTOR.

SPECIFICATION forming part of Letters Patent N o. 470,057, dated March 1, 1892. Application filed October 18, 1891. Serial No. L08,621. (No model.)

To all whom, it may concern:

Be it known that I, RALSTON C. KINTZIN G, a citizen of the United States, and a resideut of Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Dynamos er Motors, of which the following is a specification.

The object of my invention is to construct a cheap, simple, and efficient dynamo or motor; and it relates particularlyto the arrangemcnt of the frame work and field, whereby the best results are produced in the simplest mechanical form. It is of the spherical type, the armature and the iron-clad casin g being globular in form, whereby I am enabled to make not only a most efficient motor, but it also presents exteriorly a fine appearance.

In the drawings, Figure 1 is a central vertical longitudinal section of the motor; Fig. 2, a central vertical cross-section, and Fig. 3 an exterior view of one end of the same.

In constructing the invention I form the casingor shell in two parts divided centrally on a horizontal plane, the lower half or hemisphere A having a base B infegral therewith and at each end a bracket or arm, as O D, iu which the armature-shaft is journaled. The upper hemisphere E is a plain shell, and these two parts are u nited by means of screw-th readed edges, as shown, or in any other manner as, for instance, by having them fianged and bolted together. Ceutrally within these shells are screw threaded sockets to receive the screw-threaded ends of the field-magnet cores F. These field-magnets have their pole-pieces or heads G cup-shaped, the curved sockets in the ends being cut out to conform to the shape of the spherical armature. The base II of the core is designed to fit snugly against the inner side -of- -the shell. The arinatureshaft I, which passes horizontally through these shells, has centrally within a spherical armature-core I', and wound thereon in any suitable manner is the insulated wire, any form of winding being adapted for the purpose.

In Fig. 1 I show the shaft and armaturecore covered With insulated wire, as shown at J, and connected up With the commutatorplates K, and one of the field-magnets is also wound, as at L; but I have made no attempt to connect. up the wires, because the manner of connecting same forins no part of my iuvention.

My invention has particular reference to the construction and arrangement of the ironclad frame or shell and the manner of making and attaching the field-magnets thereto.

Both the fields and the armature may be wound as desired; but I prefer the ring type, with the outer surface spherical in shape and the in ner surface flat. The coils are either wound on the ring by hand or are slipped on after being wound, and the whole armature is fastened to the shaft by means of a nonmagnetic spider, or in any wa'y that will prevent its resting on the shaft; or it may be composed of a hollow spherical core, over the outer surface of which is wound the wire after being insulat-ed from the core. The field-core is preferably covere'd with copper before -being wound, and the wires may be wound directly on the core or on a spool and afterward slipped on.

By employing a spherical frame connecting the field -magnets, as shown, a perfect magnetic circuit is made, eliminating magnetic leakage, and by spherical poles and armatures the lines of force are concentrated more directly upon the armature, as well as giving the armature a greater surface. I also claim that I am enabled to obtain by this a more intense field, slower speed, greater solidity and eiiiciency, protection to the field and armature, ease of construction, and general si mplicity in construction.

That I elaim as new is- 1. A dynamo or motor composed of a hollow spherical shell in two parts, the lower part or hemisphere having base and bracket bearings for the shaft integral therewith, the opposing field-magnets being attached to the two hemispheres, respectively, substantially` as set forth.

2. A dynamo or motor composed of a hollow spherical shell to constitute a frame having` within the field magnet'cores removably attached to the shells, substantially as set forth.

3. A dynamo or motor having a hollow spherical frame, field-magnets within said shell, having hemispherical pole-pieces, and a spherical armat-ure-core, substantially as set forth.

i. A dynamo or motorhaving a frame com- ICO posed of twohollow hemispheres Secured together,` field magnets removably attached within and provided with hemisphericai polepieces, and a spherical armature -core, substantially as setV forth.

5. The combination of two hoilow hemispherical shells constituting a frame for a dynamo or motor, joned together on a horizontal plane, a -base and journaI-bearing arms cast With the lower portion, a horizontal armature-shaft journaied in said arms, a removable field-magnet vertically disposed and attached to each hemisphere within,and a spherioal armature -core on said shaft, substantially as setforth.

Signed at Brooklyn, in the county of Kings and State of New York, this 23d day of May, A. D. 1891. v
